Topic: Selintra and others, Sail and R2

[Franco]

Yeaiiieee, we finally ordered an E1 trunk. It'll be an R2 signaling (MFC R2).
I took a read at this url, and I have a feeling I won't be able to use SAIL in it's native way.
My card is an TE110P.
Does anyone have any experience with this hardware, this signaling protocol or anything related?
Thanks,

[SARK devs]

Shouldn't be a problem.  SAIL (2.1) will, by default, set the card up for E1 Qsig but you can override that in PCI cards panel to set it to whatever you want.  Set your card jumpers for E1 and you should be fine.

In 2.3.8(ish) you have even more freedom to change the generated hardware setup.  PCI cards panel is completely different in these releases so you may want to check it out.

Thanks a lot Selintra,

Is that something to come?
I'm running:

Code: [Select]

[root@servidor ~]# rpm -q sail
sail-2.3.1-4


[SARK devs]

Yes - it's what we are using here on our own PBX at the moment.  It'll be a week or so in shakedown but it's definitely getting there.. (sorry - release is 2.3.1.8 )

Hi Selintra,
I finally have tried to set up the card, without success at first

The system detects the card:

But as I read in this chapter, querying the channels returns nothing:

And the trunklines:

Should I have all the 32 channels listed?

Thanks,

Your kernel modules have not been loaded. 

The kmdl loader is a separate entity in 2.3.  Make sure you start dahdi the first time through, or simply reboot the system.  kmdls are loaded by doing /etc/init.d/dahdi start.   We noticed this issue for the first time on a fresh install yesterday and we have included a note into the 2.3(dahdi) installation quick notes.

For regular ISDN30e you should only have the Group listed because you can't "fix" or reserve  channels (for example for fax or data) in the way you could with DSS, so addressing individual channels is meaningless, it's just a 2Megabit symmetrical pipe (30B+1D@16) with each B-channel running at 64K.  Let me know if your E1 R2 signalling is different.

Very well Selintra, following the above got me the channels listed.

[Franco]

Still having problems, the link doesn't get stablished.
The provider is telling me that I'm not passing the necessary signaling, MFC-R2.

[SARK devs]

I'm afraid I can't help you much there because we've never done anything with R2.  You will need to set the correct values in /etc/dahdi/system.conf and then reload chan_dahdi, or restart asterisk, each time until you get synch.

Are there no examples on the web?

Selintra,
They just called me and are saying I need this http://www.libopenr2.org/, and that it's already part of the latest asterisk.
I'm reading all about before I start playing.
Any help is much appreciated.

Thanks,

[Franco]

Ok, I finally got it all running.
It was a signalling problem, together with me not knowing how to make a RJ48C cable 
I'll document the entire process and post in the Wiki for those who need.
Thanks a lot!

[SARK devs]

Well done Franco!

I'll look forward to seeing what you;ve done.

Selintra, I'm still having problems with this
Today I'll do a bit different to make my life easier and stop guessing the parameters: I'll install an asterisk distribution that already has support for this signaling protocol, copy all the configurations and try again with SAIL.
I'll keep you posted.

Thanks,

[SARK devs]

OK

Keep us posted

S

[SARK devs]

Bump...

Did you get this running yet?
